The benchmark rate for home loans remained in free fall in the most recent week in the wake of lackluster economic data that hinted the central bank may be slower to raise interest rates than it expects. The 30-year fixed-rate mortgage averaged 3.94%, down one basis point during the week and marking a fresh 2017 low. The 15-year fixed-rate mortgage averaged 3.19%, unchanged for the week. The 5-year Treasury-indexed hybrid adjustable-rate mortgage averaged 3.11%, up four basis points.
